In a display device, attached to a plate-type chassis ( ) is a PDP ( ) having a display screen on which videos are displayed and a circuit board ( ) on which a circuit driving the PDP ( ) is arranged. The circuit board ( ) is shielded with respect to the PDP ( ) thanks to the chassis ( ), and thus does not receive any unwanted radiation noise radiated by the PDP ( ). The display device further includes a back cover ( ) and a cabinet ( ) each having conductivity. The back cover ( ) and the cabinet ( ) house therein the PDP ( ) and the circuit board ( ) attached to the chassis ( ). The back cover ( ) and the cabinet ( ) are both electrically insulated from the chassis ( ). Therefore, any unwanted radiation noise from the PDP ( ) and the circuit on the circuit board ( ) is stopped leaking to the outside.
